SOFA-BED.

Specification of Letterstiatent. Patented Jan. 18, 1910.

Application flledluly 27, 1909. Serial No. 509,790.

To all whom it may concern:

Beit known that 1, PAUL THoRBJonnsn a subjectof the King of Norway, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful 3 Improvement in Sofa-Beds,of. which the;

following is a specification.

My inventionrelates particularly to combination sofas and beds, or combination couches and beds, in which a foldable mat-' tress-frame is' normally housed within the main frame. beneath the seat of the sofa and equipped with a flexible bed-bottom, or wire mattress, the parts being so related as to afford room between the sections of the folded mattress for thebed, 2'. e., the mattress-pad,

bed linen and covers.

manufactured at very moderate cost, but" nevertheless affording a very satisfactorysofa in one form, and every comfortable bed when in another form.

The invention is illustrated in its preferred embodiment in the. accompanying drawings, in which- Figure 1 represents a sectional view of myimproved sofa-bed in the open or bed position; Fig. 2, a similar sectional view showing the structure n closed condltion;

Fig. 3, anenlar d detail sectional view' taken as indicate at line-3 of Fig. 1; Fig. j 4-, a perspective View showing. the hinge-'2 members employed to connect the front portion of the sofa-seat with the main frame;

showing the structure in bad form; and Fig; 6, a sectional viewtaken as indicated at line 6ofFig.1.

In the construction illustrated, A represents a main frame; B, 'a. Stationary back supported by the end-standards of the main frame; G, a seat pivotally connected at its a standards 1 usually are of ornamental form and shaped at their upper ends to provide arms '1 for the'sofa.

The back B is disposed between the rear upper portions of the end-standards 1, be-. ing rigidly connected therewith in any suitable manner.

The seat C comprises a frame and cushion 6. The front portion of the frame 5 is provided, at the ends of the frame, with hingemembers 7 having trunnions 8. Se cured to the inner surfaces of the end-standards lare clips, or hinge members, 9 having in-struck bosses, 10- provided with vertical slotsll adapted to receive the trunnions 8.

The slots 11 are open at their upper ends, so

that the seat may be lifted out of its bearings.

The bed-frame D comprises a front section 12; a rear section 13; and an intermediate section 14. The section 12 normally depends, when the structure is in the sofa form, beneath the seat-frame, being rigidly attached thereto. Said section comprises end members 15 which are preferably of angle-bar form. The end members 16 of the seat-frame 5 have downturned extension-s 17 to which the'members 15 are se-. cured. An angle-bar truss-member 18 is secured to the rear lower corner of the seatframe and has at its extremities depending arms 19 connected with the extremities of the members-'15. The front ends of the downward extensions 17 are connected by braces with the main portion of the seats frame 5.

The intermediate bed-section 14 comprises end members 21 of angle-bar form having their upper or front extremities connected, by pivots. 22,- with the adjacent ex- Fig. 5, a broken horizontal sectional view s front portion with the front portion of the main frame; and D, a foldable bed normally I housed in folded-condition within the main frame beneath the seat C.

' The frame A may be of any suitable construction. As shown, it comprises endstandards 1; a front connecting member 2,

and arear cormecting member 3. The end-- i'longitudinal web 26' and forwardly-extendmg end members. or arms, 27., This U- shaped member is preferably of angle-bar construct1on.. The extremities of the arms 27 are connected, by bolts28, with the adj acent extremities of the members 21 and the extremities of the arms 24. faces of the end-standards 1 of the main frame are equipped with'pivot-blocks 29 to which are pivotally joined links 30 whose 'The inner su-rguides, 31* adapted to" receive the downtruss 23 ofthe intermediatebedrsection when,

the bed is inthe extended position, and the 'tu-rned flanges of the end members 27 of the rear bed-sectiom'as willbe clearly under-- stood from Fig. 3. Links 32 are'connected, at'their rear ends, by pivots 83,.with the links 30, near the freeends thereof, 'and, are

connected, at theirf-ront ends, by pivots, or 'bolts, 34%,with armsj35 rigldlyseoured to the extremities of: the end members 27" of the' rear bed-'section. r The upperedgeof the front connecting 1nemb er 2 ofthe mainframe is preferably rounded, or beveled, as indicated atv 36. Said upper edge affords albearing for the purpose of the bevel 86' is' to enable the; truss attained in the manufacture of the struc-,

23/00 move properly onto its bearing when the structure'is converted from sofa form to bed, form; Said-truss is provided with projections136 which rest upon the inverted seat-frame. The bearings 36 are. adapted to rest withcertainty on the'seat-fram'e, even though great accuracy ofconstruction-is not ture.

, Connected with the end-members ofthe three bed sections is a fleXible'bed-bottom,

or wire mattressf37, adapted to foldand unfold with the folding and unfolding of the bed frame. 'At the extremities of the front and rear bed-sections are members, or standards, 38,- adapted to confine the bedpad, or mattress proper, longitudinally. In

Fig. 2, the bedding 39 is indicated in' the folded condition by dotted lines. Thelinner surfac'esof the lower portions of the end-standardsl of the main frame are equipped with stops 40 adapted to support the links 30 in the folded condition of the structure.- may be employed for securing the bedding to the bedframe.

The operation will-be readily understood from the foregoing description. The bed is made up while the structure is in the open position shown in Fig. 1, and the structure is then converted to sofa form by swinging the seat rearwardly to the position shown in Fig. 2. When the seat is swung to the folded osition, the front bed-section, which is rigi ly attached to the seat, is carried to the depending osition shown in Fig. 2, and the truss 23 of the intermediate section is carried off the bearing afforded by the upper edge of the front connecting member 2 of the main frame, and the rear bedsectlon 1s swung rearwardly and downwardly, 1nwh1ch movement it is carried by the links '33 whose upper ends slidably engage the end members of the rear bedframe section and the links 32 which connect the llIlkS 30 with the arms 35 carried by the front extremities of the end members Any suitable means (not shown) free ends areprovided with channels, or 1 of the rear bed-section.

=mediate bed-section is carried bodily from its bearing on the main frame and lowered to the position shown in Fig. 2. In the reversev operation, the seat is swung from the position shown in Fig. 2 to the posltlon shown in Fig; 1, carrying with it the front bed-section, which, in turn, actuates the intermediate and rear bed-sections, the links 30swinging orwardly and upwardly and carrying the rear bed-section.

-. v The construction described is simple, dura-.

ing the trunnions 8 from the bearings l1.

Thisis frequently of convenience in transporting thestructure, as in moving from one house to another.

.The foregoing detailed description has been givenlfor clearness of understanding only. Hence, no undue limitation should be understood therefrom,but the appended claims should be construed as broadly aspermissible in view of the prior art.

What I regard as new, and desire to secure by Letters Patent, is

Thus, the inter-' I 1. In a structure of the character set forth,
